Chassis
REAR WHEEL RIM
•
Using a dial gauge, check that the ra-
dial (A) and the axial eccentricity (B) of
the rim (2) do not exceed the limit val-
ue.
An excessive eccentricity is usually caused by
worn or damaged bearings. Replace the rim (2) if
after replacing the bearings, the value is not within
the specified limit.
Characteristic
Maximum radial and axial eccentricity:
0.5 mm (0.0197 in)
FINAL DRIVE UNIT BEARINGS
Carry out the check with the bearings fitted on the final drive unit.
ROTATION CHECK
•
Remove the left spacer.
•
Remove the right spacer.
•
Manually rotate the inside ring of each bearing. Rotation must be constant, smooth and
noiseless.
If one or both bearings do not fall within the control parameters:
•
Replace both bearings of the final drive unit.
RADIAL AND AXIAL CLEARANCE CHECK
•
Check the radial and axial clearance. Axial clearance: a minimum axial clearance is allowed.
Radial clearance: none.
If one or both bearings do not fall within the control parameters:
•
Replace both bearings of the final drive unit.
FLEXIBLE COUPLING
Check that the flexible couplings (3) are not dam-
aged or excessively worn.
To check:
•
Position the complete final drive unit on
the wheel.
•
Manually rotate in both directions the
flexible coupling disc (4) and check the
clearance between the flexible cou-
